Unit 3 Vocabulary

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which particles move back and forth in the same direction that the wave travels, or parallel to the wave.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another.

Front

What happens when a wave bounces off a surface?

Back

When a wave bounces off a surface, it is called reflection.

Front

What is transmission in the context of waves?

Back

Transmission is when a wave passes through an object or medium.

Front

What is the medium in wave terminology?

Back

The medium is the material through which a wave travels.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave in which particles move perpendicular to the direction of the wave's travel.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, changing its speed.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, reducing the wave's intensity.

Front

What is amplitude in wave terminology?

Back

Amplitude is the maximum distance that particles in a wave move from their rest position.

Front

What is a crest in wave terminology?

Back

A crest is the highest point of a wave.
